In order to test these patches, we require Linux with KVM AIA support which can be found in the riscv_kvm_aia_hwaccel_v1 branch at https://github.com/avpatel/linux.git --- v6: - fix alignment - add hart index to the error message of ISMIC address setting in PATCH3 v5: - remove the linux-header update patch since the riscv-to-apply.next QEMU has synced up to Linux 6.5-rc1 headers. - create the APLIC and IMSIC FDT helper functions in PATCH1 - add the irqfd support in PATCH3 - fix the comments and refine the code v4: - update the linux header by the scripts/update-linux-headers.sh in PATCH1 - remove the checking for "aplic_m" before creating S-mode APLIC device in PATCH2 - add more setting when we initialize the KVM AIA chip in PATCH4 - fix msi message delivery and the APLIC devices emulation in PATCH5 - fix the AIA devices mapping with NUMA enabled in PATCH6 - add "kvm-aia" parameter to sepecify the KVM AIA mode in PATCH6 v3: - fix typo - tag the linux-header patch as placeholder v2: - rebase to riscv-to-apply.next - update the linux header by the scripts/update-linux-headers.sh Yong-Xuan Wang (5): target/riscv: support the AIA device emulation with KVM enabled target/riscv: check the in-kernel irqchip support target/riscv: Create an KVM AIA irqchip target/riscv: update APLIC and IMSIC to support KVM AIA target/riscv: select KVM AIA in riscv virt machine hw/intc/riscv_aplic.c | 56 ++++-- hw/intc/riscv_imsic.c | 25 ++- hw/riscv/virt.c | 410 ++++++++++++++++++++++----------------- include/hw/riscv/virt.h | 1 + target/riscv/kvm.c | 170 +++++++++++++++- target/riscv/kvm_riscv.h | 6 + 6 files changed, 469 insertions(+), 199 deletions(-) -- 2.17.1
